ZWO ASI120MM Mini

Is the ZWO ASI120MM Mini a good pairing with the william optics 50mm guidescope.

It’s more a case of whether your guiding setup is suitable for your imaging setup. In most cases this is a good guide camera/scope set up. You can check your imaging setup against guiding by going to Astronomy tools (in the drop down menu) and scroll down finding the guiding suitability calculator. I’ve use mine on focal lengths from 250mm upto 1500mm.

I was guiding OK with the ASI120MC-S, which has some downsides to what you are proposing:

1. Mine was colour, not perfect for guiding, mono is better which is what you suggest.
2. Mine was on an OAG, less light, with a 50mm Guidescope, you'll get more light, but also other issues like flexure, but a 120MM/MC is likely to be ok.

I just got myself a ASI290MM mini, this is a level above the ASI120MC-S, but I do not regret taking the route I took to the point where I could afford what I have now.

I use the this camera but with the skywatcher 9x50 guide scope and so far it's pretty good with my es ed80.

What's been started above really, depends on what imaging train you will be using. I'm using one connected to a sw star travel 90 to guide a sw 130pds and dslr and its excellent.

Yes it is a great combination. I use it on a WO ZS103. I think it may be good up to 1000mm focal length of main scope. Maybe beyond.
